This is the precise reason why "route" is pronouced "root" but "router" is mysteriously pronounced "raow-ter". No-one's gonna stand in front of a room full of people and talk about the "rooter".
Actually, this varies with dialect. Route can be pronounced either way: |ˈrüt| or |ˈrau̇t|

Btw, why is it "pronUnciation", but "pronOUced". English is hard.
In Australian English, it is "pronOUNCiation"
BTW, in case there has been some confusion here, since the topic was how things were said, I have been assuming this is what the person I was replying to was talking about, not spelling.
